Use of morphoj soft package for phenotypic and genotypic variety testing (English oak case study)

Abstract

Summary: Background. Some special characters in asymmetry of shape were studied in leaf plate English oak. Materials and methods. In 6 random populations generalized Procrustes analysis showed the mix of fluctuating asymmetry (FA) and directional asymmetry (DA). Results. One population showed pure FA. Covariance symmetric matrix reveals more variance in comparison to matrix asymmetry showed variation bilaterally symmetrical landmarks. Correlation analysis of covariance symmetric matrix and matrix asymmetry containing the coordinates of landmarks after the permutation showed a weak positive correlation coefficient (0.25, p < 0.01). Conclusion. The coefficients of variation of the factors “side”and “side × population” among 6 populations were respectively 48.24% and 44.93% that evidenced on equal variance of both types of asymmetry or slightly increased directional asymmetry. It is noted that the cluster analysis the matrix asymmetry can be used to search genotypic variability.
